6304-Z/C4 Bearing Product Overview & Core Advantages
The 6304-Z/C4 is a single row deep groove ball bearing engineered for high-performance applications requiring reliable radial load capacity and operational stability. This metric bearing features a shielded design (Z) for contaminant protection and is supplied with a C4 radial internal clearance, making it exceptionally suitable for applications involving thermal expansion or where interference fits are used. Its ABEC 1 | ISO P0 tolerance ensures consistent quality and smooth operation, offering an optimal balance of performance, durability, and value for demanding industrial environments.
6304-Z/C4 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance & Advantage |
|---|---|---|
| -Z | One side shielded | Provides effective protection against large particulate contaminants while maintaining low friction and high-speed capability. |
| /C4 | Greater than normal radial internal clearance | Accommodates thermal expansion in the shaft or housing, prevents preload in high-temperature applications, and is ideal for tight interference fits. |
6304-Z/C4 Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The single row deep groove raceway and high-quality chrome steel construction provide a high radial dynamic load rating of 3574 lbf, ensuring long service life under substantial radial loads.
- Shielded Protection: The shielded (Z) design effectively retains lubrication and excludes larger contaminants, enhancing bearing reliability without the added torque of contact seals.
- Thermal & Fit Adaptability: The C4 radial clearance is a critical feature that prevents binding and reduces operational noise and heat generation in applications subject to significant temperature fluctuations or where press fits are required.
- High-Speed Operation: With a limiting speed of 14,000 rpm, this bearing is capable of supporting high rotational speeds, making it suitable for a wide range of industrial machinery.
6304-Z/C4 Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors and Small Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring robust and reliable ball bearing support
